1 Claim. (Cl. 40-23) The present invention relates to a combinationpaper clip and a marker for books.

In general use today are metal clips and in some respects these clipsare not satisfactory for the reason that due to the smoothness of themetal they do not hold firmly to papers, or to pages of books markingcertain pages in books. Due to the smoothness of the metal the clips aresubject to casual displacement.

It is an object of the present invention to provide a paper clip thatwill grip paper and hold it securely.

Another object of the present invention is the provision of a roughened,grooved, corrugated or spiral grooved surface on the elements thatconstitute the clip.

A still further object of the present invention is the provision of aclip that may be provided with a slip of paper having indicia thereondirecting the papers to a particular person, or indicating thedisposition of the papers.

A still further object of the present invention is the provision of apaper clip made of polyethylene or other suitable plastic material.

A still further object of the present invention is the provision of apaper clip having one element longer than the other.

A still further object of the present invention is the provision of apaper clip that may be made in diiferent shape and sizes, two differentstyles being shown in the drawing.

Other objects and features of the invention will be more fullyunderstood from the following description in the application in whichdescription reference is made to the accompanying drawing in which:

Figure 1 is a front elevation partly in section.

Figure 2 is a side elevation.

Figure 3 is a view similar to Figure 2 and illustrating sheets of paperheld by a clip.

Figure 4 is a front elevational view of a modified form of the clippartly in section.

Figure 5 is a rear view of the circular disk shown in Figure 4, and

Figure 6 is a fragmentary sectional view taken on line 6-6 of Figure 1looking in the direction of the arrows and showing the grooves andcorrugations.

Referring to the drawing Figures 1, 2, 3 and 6, the numeral 10represents a clip of polyethylene or other suittable material that willgrip paper, and it comprises a back oblong element 11 having one face 12roughened or grooved, the grooves 13 being in crisscross formation,having apices 14, and adjacent the bottom edge 15 there are providedhorizontal grooves 16, having rounded top portions.

Secured to the element 11, by a staple 17, or by other suitable meanssuch as acetate, is element 18 that has one face 19 roughened 0rgrooved, the grooves 20 being in crisscross formation and having apices21. By securing elements 11 and 18 together by a staple or othersuitable means adjacent the top edges 22 and 23 respectively of theseelements, a space 24 shown in the drawing as exaggerated is providedbetween the inner faces of the elements from the top edges 22 and 23down to the point of juncture and in the showing by a staple. Into thisspace is inserted a slip of paper as indicated by the dotted lines inFigure l, the slip of paper being shown exaggerated. On the slip ofpaper is placed indicia directing to whom the papers are to go, or whatis to be done with them.

In the modified form of the invention shown in Figures 4 and 5, element30 is of elongated configuration, having its ends 31 and 32 rounded. Theinner face 33 being provided with a plurality of radial grooves 34.Secured to the element 30 by staple 35 is a circular disk 36, the innerface 37 of which is provided with concentric grooves 38. By staplingelement 30 and disk 36 at the point shown in Figure 4, a space isprovided similar to the space 23 for the reception of a slip of paper asshown by dotted lines 39, the slip of paper having indicia as previouslyenumerated in describing Figure 1.

In use of the clip as shown in Figure 3, a number of sheets of paper areheld together by fingers of one hand and the clip brought intoengagement with the papers by the other hand, or vice versa, portions ofthe elements 11 and 13 below the staple yieldingly allowing theseelements to get a firm grip on the papers, the apices 14 and horizontalgrooves 16 preventing casual displacement of the clip from the papers,the grooves 13 and 20 forming substantially suction pockets due to thecrisscross formation of the grooves.

In use of the clip shown in the modified form Figures 4 and 5, theelement 30 and circular disk 36 below the staple 35 yield to theinsertion of papers between the ele-' ments, the radial grooves 34 andthe concentric grooves 38 preventing casual displacement of the papers.A slip of paper 39 is inserted between the elements 30 and 36 above thestaple with directive indicia.

The described forms of clip shown are well adapted to carry out theobjects of the present invention, it is to be understood thatmodifications may be made within the spirit of the invention.

What is claimed is:

A paper clip of plastic material comprising separate front and backelements stapled together at a predetermined median point, an openindicia receiving area formed above and between said elements bystapling at said predetermined point, said back element being longerwith respect to the front element and having horizontal grooves at itspoint adjacent the lower end of said front element, said horizontalgrooves having rounded top portions, crisscross grooves on the innerface of said front element, and crisscross grooves on the inner face ofsaid back element above said horizontal grooves, all of said crisscrossgrooves having sharp edged top portions, said rounded top portions onsaid horizontal grooves allowing papers to be initially easily insertedbetween said elements, and said sharp edge top portions on saidcrisscross grooves holding said papers firmly after insertion.
